How exiGrow works

How it works

exiGrow dissolves hardened minerals and softens clay that block water, air, and nutrients essential for strong, healthy roots.

Solves common problems

- Patchy lawn

- Dry sections--especially on slopes

- Water pooling or running down gutters

No more messy aeration

Avoid the expense and hassle of mechanical aeration. In addition, aeration damages the roots and doesn't release the essential minerals in the soil that plants crave. Nothing is better at restoring your healthy soil.

Simple to apply

Just spray on your lawn and garden each month during your growing season by using any standard hose-end sprayer.

Commercial clients report reducing water use up to 40% and fertilizer use up to 70% since more of both get absorbed into the soil rather than running down the gutter.

Hundreds of the finest golf courses, sports stadiums, and resorts around the world enjoy the benefits of the exiGrow solution.

Used by the pros

Same patented advanced technology used by professional groundskeepers since 2006.


Vital to how I keep my turf healthy.
— Lance Larson, Wasatch Park Golf
This is a staple in the golf industry.
— Monica Cooper, CGCS Smyrna Golf
We have noticed better turf color, thickness, and overall health from traditional acid methods we’ve tried, and we use less water and have fewer dry spots.
— Curtis Hirache, SLC, UT Superintendent
Eximo has proven itself to be a top performer among soil amendment products. Our experience has shown it to be an economical tool and a valuable asset in extremely challenging situations.
— Rob Cleer, Florida GC Superintendent
We saw a great color response on our greens after only one application.
— Gary Cudney, Odessa, TX Superintendent
We use the solution to make both pro and junior league sports fields playable sooner when rain outs are a problem by breaking up the bicarbonate bonding in the top inch of the soil surface.

Seminole GC

Heavy accumulation of mineral salts killed the fairways and looked like snow. One application per week over 3 weeks helped to dramatically improve color and coverage.

An HOA client gave up on aeration and began applying exiGrow to a section that never filled in before.


What's the secret sauce?


ExiGrow contains the proprietary active ingredient Syntech, a patented acid replacement technology that has the power of 0pH but is 100% safe.

The other ingredients include natural wetting agents that help to spread the solution and water through the blocked soil.



Frequently Asked Questions


How do I apply exiGrow?

  1. Pour the amount of exiGrow you want to apply into the tank of most any standard hose-end sprayer.
  2. Set the dosage to between 4tsp up to 8tsp per gallon (use higher dose for first application each year and if the area to be treated is severely blocked.
  3. Lightly spray on lawn and gardens (don't apply in direct sunlight to avoid evaporation).
  4. Immediately soak in with a 1-minute sprinkler cycle.

How does exiGrow work?

The main ingredient that we call Terranex is a patented natural acid replacement. The chemistry of how this loosens your soil is pretty basic. Hardened alkaline minerals compact your soil and block the water, air, and nutrients. exiGrow safely solubilizes these minerals making them available for uptake by the plants and opening up the soil. If you've ever made a volcano for your child's school project and poured vinegar over baking soda, you've seen a similar chemical reaction.

Do I still need to aerate?

No! ExiGrow replaces and enhances aeration. No more hours pushing a gigantic machine under the hot sun. Simply attach exiGrow to your hose and spray!

How long has exiGrow been used for soil treatment?

Professional groundskeepers for PGA-level golf courses and major sports stadiums have been using our natural solutions for many years. In fact, the PGA uses the exiGrow technology (our commercial version is called Eximo) on its course, Valhalla Golf Club, and recommends it to the schools teaching its groundskeepers training program.

Will I still need to water and add fertilizer to my lawn?

Not as much or as often! ExiGrow allows all the nutrients your grass needs to get down to the roots, maximizing the effects of water and fertilizer.

Is exiGrow Safe?

The patented all-natural solution is free of harmful chemicals, is 100% biodegradable in 10 days, and is certified safe for people, pets, the planet, and, of course, your plants by Cleangredients, Green Circle, and has an HMIS (Hazardous Material Identification System) rating of triple 0 (no hazard). 

How can so little exiGrow cover so much area?

Each 16 oz bottle of concentrate treats up to 11,000 sq.ft. (1/4 acre).  You spray it on your lawn and gardens at a dosage of about 150:1 (150 parts water to one part solution). This requires a dosage setting on your hose-end sprayer of 1oz per gallon. 

Apply once per month during your growing season. You may want to apply a double dosage for your first application and in the heat of the summer when your ground is driest and hard. 

Do I still need to fertilize and use weed killer?

You should continue to water, fertilize, and control weeds. You should eventually be able to cut watering up to 40% and fertilizing up to 70% since more of both is being absorbed into the soil instead of running down the gutter. BIG SAVINGS!

If I use my own sprayer, what dosage setting do I use?

You can pour exiGrow into any standard lawn and garden sprayer and set the dosage to between 4tsp and 8tsp per gallon depending on the condition of your soil. 

When would I apply your product on Tall Fescue?  Each time I fertilize?

How much you should use depends on the condition of your soil, i.e., the extent of compaction due to the hardened minerals or clay. Generally, we recommend treating the soil at least once each month during your growing season. Your first application and/or during the driest period of summer, you may want to do a double dose.  

If my lawn is currently struggling to withstand the heat and dollar spot, would this help it survive the summer?

By dissolving the minerals and opening up the soil, exiGrow will help your lawn absorb more water and fertilizers benefiting it especially during the hot, dry summer months.

In the fall, should I put this down with seed and starter fertilizer and water it in all together?  Or should I apply the Exigrow first and let it do it's work for a couple days before laying seed and fertilizer? 

If you’ve been applying exiGrow each month, you could fertilize and seed simultaneously in the fall, but spraying exiGrow ahead will prep the soil. 

Are there third-party reviews anywhere?  I googled you and nothing came up.

The exiGrow solution has been available commercially for about 15 years, but we’ve just begun to offer it for home use. You should find information about the commercial version called Eximo. 

Does exiGrow replace the need to lime, and does it include a surfactant?

exiGrow uses the same formulation as Eximo and can replace lime and other acid soil treatments. The solution is based on a patented acid replacement technology that gives you the low pH benefits without the harmful effects, e.g., corrosiveness. Farmers use the solution around the base of their fruit trees in the orchard and other crops instead of sulphuric acid since the exiGrow solution won’t harm the plants. exiGrow also includes a natural wetting agent to help spread it and water and nutrients through the soil. 

Is exiGrow safe for my food gardens?

exiGrow is definitely safe for your lawn and food gardens. The ingredients are 27% Palm Methyl Esters, 5% Coconut Oil Fatty Acids, and 68% inert ingredients, which includes our patented technology we call Terranex. It is certified HMIS triple 0--no danger to health, flammability, or physical contact--and is 100% biodegradable within 10 days. Farmers have been using our solution for many years.

Is ExiGrow safe to use on St. Augustine grass?  Also, can I still use a weed control product when necessary?

exiGrow is completely safe to use on all types of plants. You should continue to use weed control and fertilizers as usual; however, exiGrow will boost the benefit of fertilizers up to 70% and cut water usage up to 40% because of the more porous soil. 

Have any third-party studies been performed?

Absolutely! In addition to our hundreds of commercial customers vetting the solution, they have commissioned many studies for efficacy and safety. Click here for a sampling and more information regarding our active ingredient Syntech.


What our customers are saying ...

I’ve spent years watering this stuff onto greens as a golf course maintenance grub. Yes it works
— Jae, WY
So far I’m impressed. I will be buying more. Going to use it all winter well into spring before planting.
— Seth
This product is amazing! It changed our yard into a beautiful green lawn. We had brown patches that we could not get rid of. We had tried everything. This was a last effort and we didn’t really expect it to work but it did! We have already ordered more!
— K. Kirby
this stuff really works my lawn really looks beautiful
— W. Gamble
I wish I had taken before and after photos. I have three spots in my front yard that go brown every summer. It doesn’t matter how much I water and fertilize it. I took a chance on TruGrow and couldn’t be happier. I noticed a difference in two days! I am now a week into and the results are incredible! I’m still shocked!!
— S. Ringger
Worked for me
— Ab, TX
😁 If only there was a weed killer that worked as well.
Wow, truSpring!!! My grass is looking great. Good stuff. I think the problem with our soil in NC is because of the fly ash from coal burning electric plants changing the pH and causing the topsoil to be compacted in this area but Exigrow is correcting the problems.
— Derrick, NC
I live in San Antonio and used it last summer. I definitely noticed a difference. I need more.
— Robert, TX
Bought it, used it, and it worked awesome!
— Matthew N.
I stumbled upon this and I have been shocked... this stuff has made a major difference in my yard, I’m amazed!
— D. Makin
My lawn has never looked better!
— Emily, Utah
Ok i now see a difference. It doesn’t happen overnight. I applied half the lawn and about three weeks later it IS greener. I’ll mow and take pictures.
— M. Hall
Works like a champ!
— Matt K.
I applied this 2 weeks ago. So far my grass is back green where it had turned brown and the patchy spots are going away. My yard is looking pretty good. Can’t wait to reapply in early spring.
— Tamica C.
I guess I’m one of the lucky ones? I have HEAVY clay soil. I’ve been struggling to get the grass to grow in a section of my yard. The rest of the yard does ok with a few yellow and dry areas. I bought one bottle to test. I used half the bottle on the first treatment. The rest on a second treatment one month later. The first thing I did was pour a little right from the bottle on the exposed ground. It did indeed foam up like the video. After the first application, I noticed my trouble area was not much better. However the healthy areas were doing far better, color was nice and green and the “good” grass was growing great. About a week after the second application, my yellow areas started turning green. My trouble area is still troubled, but I’m starting to see small green blades popping up. I’m convinced enough that I’ll be buying the three pack and starting early next spring.
— Dale M.
This freakin’ thing really works. It pisses me off that I have to mow my lawn twice a week now. It’s a bad thing but it’s a good thing.
— Rolando C.
It’s working for my lawn there wasn’t a green blade of grass on this patch of soil look at how it’s grown back and it’s almost all filled in and greener, there was only yellow grass when I purchased the place.
— Juan M.
Didn’t know how this was going to work or if it would work for my lawn but it did. We had a brutal summer with temperatures at 100 degrees or near that for weeks and I was having to water almost everyday. My lawn was taking it on the chin from the heat as well as the pocket book and water trying to get into hard, clay soil that runs through my yard. I saw your ad and thought, why not give it a try. I am so glad I did and I have recommended your product to my son and want to use this at my second home as well since my lawn came alive and I was able to cut back the watering to 3 times a week and the grass is so green, neighbors have commented on how nice it looks.

Thank you for such a fine product that does what it advertises. I will be a return customer from now on. Anyone wondering if this really works, it does and you won’t regret buying it. 
— Jim & Valerie B.
Your product is wonderful. It seems to have solved my lawn problem. No more dry spots and the grass has greened up so well. I am looking forward to next season to see if the magic continues.
— Lynn S.
Have only done two applications and the lawn looks greener already!  Great product!
— Sally G.
The difference is AMAZING between mine and my neighbor’s grass.
— Nicole M.
Love the way it makes my yard look. It’s so easy to spray on… And none of those plugs.
— Mary, UT
Yes, no lawn turds!
— Miles, TX
Wow! Very impressive.
— Kelly S., TX
About a week after the second application, my yellow areas started turning green. My trouble area is still troubled, but I’m starting to see small green blades popping up. I’m convinced enough that I’ll be buying the three pack and starting early next spring.
— Dale M.
— Jim W.
Hello : I was skeptical about trying this product, but went ahead and purchased the 3 bottle pack and the ortho hose sprayer, I received my delivery promptly and applied the product, I have pretty high content clay soil here in Pennsylvania, after about 5 days I mowed my lawn and in the next few days we had some rain I was sitting out back and noticed that my grass looked much darker green and healthy before treatment my grass color was fading to a yellowish green, a few hours later when my wife arrived home from work she came out back and the first thing she said was wow look at are grass it looks great, she really never comments on it, I am convinced that this product has worked for me
— Robert D.
I would put this on even if my soil was close to perfect.
— James D.
Ok it worked! FB has a lot of critics as you can see. Things that are new to people they tend to post doubting messages. I did half my lawn which is clay based soil under thin layer of top soil. I hit it every year with gypsum with the hopes of breaking up the clay. So your product works but it’s not an instant overnight change which I think most people are thinking.

People expect an instant miracle. Doesn’t work that way. Any plant life takes weeks to respond to any application. Glad I could help. My soil is clay by the way. Greened up nicely and the other half I didn’t apply is yellowed and struggling.
— Matthew H.
We live at an elevation of 7500 ft. I have only had time to use 1 bottle of your product before the growing season wound down. In that short time, I certainly did notice a difference in the lawn. It was certainly greener and I plan to start using your product next May for the growing season.
— Charles B.
WOW, I am impressed with your customer service. I will continue to use your product and will be ordering more soon. Thanks again for prompt and informative response.
— Richard
So far extremely happy with my purchase used one bottle on the front yard that had major problems this summer it now looks amazing! thank you! will be purchasing again.
— Susan N.
For years I have had a couple of dry spots in our lawn that just wouldn’t go away. This year, another one surfaced so I tried your product. The first two feedings didn’t seem to do too well, but after that, all the spots went away and have stayed away. I liked it so much that I gave the balance of my bottle to a neighbor who had a similar problem. I will probably be trying some next year as well.
— John L.
We had sewer replacement work done and our yard was packed very hard with heavy equipment.  We saw your ad for your product and decided to try it.  We only had time to use it twice and it has really got the new grass growing.  We plan on using your product during next years growing season.
— Roger
Used this on my lawn for the first time about a month ago and already I’ve noticed an improvement in color and if I didn’t know better my lawn even looks thicker as some of the bare spots have filled in. Hope this continues to improve. Good product. Thanks,
— Rick
The promised shipment of 2 bottles arrived today. Thank you for your excellent customer service!
